Abstract

"PRODUTOS DE POLìMERO COMPREENDENDO COMPOSIçõES DE COPOLìMERO DE POLIHIDROXIALCANOATO BIODEGRADáVEIS ELáSTICAS E MACIAS E MéTODOS PARA PREPARAçãO DE TAIS PRODUTOS DE POLìMEROS". Produtos de polímero elásticos e macios são obtidos alongando-se uma composição compreendendo um copolímero de polihidroxialcanoato biodegradável compreendendo pelo menos duas unidades de monómero aleatoriamente repetidas. A primeira unidade de monómero aleatoriamente repetida tem a estrutura (I), em que R^ 1^ é H, ou C1 ou C2 alquila, e n é 1 ou 2. A segunda unidade de monómero aleatoriamente repetida tem a estrutura (II), em que R^ 2^ é uma C3-C19 alquila ou C3-C19 alquenila. Pelo menos 70 % em mol do copolímero compreende unidades de monómero aleatoriamente repetidas tendo a estrutura da primeira unidade de monómero aleatoriamente repetida (I). Os produtos exibem combinações vantajosas de maciez e elasticidade ao mesmo tempo que mantendo a resistência."POLYMER PRODUCTS UNDERSTANDING ELASTIC AND SOFT BIODEGRADABLE POLYHYDROXIALCANOATE COPOLYMER COMPOSITIONS AND METHODS FOR PREPARING SUCH POLYMER PRODUCTS". Elastic and soft polymer products are obtained by elongating a composition comprising a biodegradable polyhydroxyalkanoate copolymer comprising at least two randomly repeated monomer units. The first randomly repeated monomer unit has structure (I), where R ^ 1 ^ is H, or C1 or C2 alkyl, and n is 1 or 2. The second randomly repeated monomer unit has structure (II), in that R2 is a C3-C19 alkyl or C3-C19 alkenyl. At least 70 mol% of the copolymer comprises randomly repeated monomer units having the structure of the first randomly repeated monomer unit (I). The products exhibit advantageous combinations of softness and elasticity while maintaining strength.
